<td class="sectionTableSingleCell">一种用于重复出现的问题的解决方案模板，它已被证明在给定环境中是有用的。好的模式能成功地解决问题的冲突面，根据解决这些冲突面的方式，确定一个模式优于另一个模式。模式应具有至少三个已明确的实际应用，才有资格称为模式。对于软件，UML
可通过使用参数化协作来支持模式的表示 － 尽管 UML 不直接为模式的其他侧重面（例如使用结果列表、使用示例等等）建模，可将文本用于这些方面。通过将值绑定到参数，来实例化软件模式。模式可以各种不同规模和抽象级别而存在，例如<i><a class="elementLinkWithUserText" href="./../../../core.base_rup/guidances/termdefinitions/architectural_pattern_E2E8EB79.html" guid="_x7JZRtnmEdmO6L4XMImrsA">体系结构模式</a>、<a class="elementLinkWithUserText" href="./../../../core.base_rup/guidances/termdefinitions/analysis_pattern_86D515F0.html" guid="_x613Q9nmEdmO6L4XMImrsA">分析模式</a>、<a class="elementLinkWithUserText" href="./../../../core.base_rup/guidances/termdefinitions/design_pattern_4AEB9B64.html" guid="_yF4CnNnmEdmO6L4XMImrsA">设计模式</a>、测试模式、<a class="elementLinkWithUserText" href="./../../../core.base_rup/guidances/termdefinitions/idiom_6D91029A.html" guid="_yKVr0tnmEdmO6L4XMImrsA">代码模式</a>或<a class="elementLinkWithUserText" href="./../../../core.base_rup/guidances/termdefinitions/implementation_pattern_ED414F6.html" guid="_yKpN0NnmEdmO6L4XMImrsA">实施模式</a></i>。</td>
